Remove flags low-diskspace-threshold-mb and outofdisk-transition-frequency
issue: #48843
This removes two flags replaced by the eviction manager. These have been depreciated for two releases, which I believe correctly follows the kubernetes depreciation guidelines.
```release-note
Remove depreciated flags: --low-diskspace-threshold-mb and --outofdisk-transition-frequency, which are replaced by --eviction-hard
```

Fix kubectl describe for pods with controllerRef
**What this PR does / why we need it**:
kubectl describe doesn't take controllerRef into consideration, resulting confusing result. e.g. if we have two replicaset with the same selector, one with 1 replica and the other 2 replicase, then both replicaset will show 3 running pods.
```sh
$ kubectl describe rs replicaset-2
Name: replicaset-2

Refactors and removes the need for the more complex old code,
temporarily limits what output is shown for truly unknown objects (a
follow up change will allow server side handling and generic fallback),
and removes all of the generic printers in favor of a single code path.

Remove old node role label that is not used by kubeadm
**What this PR does / why we need it**:
This label hasn't been used by kubeadm since v1.5.
v1.5 support was dropped when v1.6 arrived due to a potential security flaw and the earlier alpha status.
So this label hasn't been used for around three months.
It makes sense to remove it in time for v1.8, could already have been done for v1.7

add ContainerRuntimeVersion to `kubectl get nodes -o=wide` output
**What this PR does / why we need it**: adds container runtime version to `kubectl get nodes -o=wide` output as a way to surface more node-level information
When upgrading to a new container runtime version (docker 1.11 -> docker 1.12) or when experimenting with a different container runtime version (experimenting with rkt in a docker cluster), it's useful for cluster operators to see which nodes are running which container runtime version. `kubectl get nodes -o=wide` already provides kernel and OS version, and I believe adding container runtime version would be good.
**Release note**:
```release-note
container runtime version has been added to the output of `kubectl get nodes -o=wide` as `CONTAINER-RUNTIME`
```

hide operator when describe pod with empty value tolerations
**What this PR does / why we need it**:
The tolerations printing in `kubectl descirbe pod` is not correct when toleration.value is empty, this PR is to fix it.
Before:
```
Tolerations: node.alpha.kubernetes.io/notReady=:Exists:NoExecute for 300s
node.alpha.kubernetes.io/unreachable=:Exists:NoExecute for 300s
```
After:
```
Tolerations: node.alpha.kubernetes.io/notReady:NoExecute for 300s
node.alpha.kubernetes.io/unreachable:NoExecute for 300s
```
Also updated tests to cover all possible cases of describing pod with tolerations. See changes in of `TestDescribePodTolerations()` in `describe_test.go`

StorageOS Volume Plugin
**What this PR does / why we need it**:
This PR adds a new volume plugin for StorageOS volumes. StorageOS runs as a container on Kubelet nodes, aggregating local or attached storage and making its capacity available to all nodes within the cluster. More information at http://storageos.com.
The StorageOS plugin supports:
1. Dynamic Provisioning using Storage Classes
2. Persistent Volumes and Persistent Volume Claims.
**Which issue this PR fixes**
A feature request has been created:
https://github.com/kubernetes/features/issues/190
This isn't on the schedule for 1.6 as I wasn't sure when it would be ready. We intend to make the StorageOS container openly available within the 1.6 lifetime.
**Special notes for your reviewer**:
Separate commits for feature and godep changes.
**Release note**:
```release-note
StorageOS Volume Driver
[StorageOS](http://www.storageos.com) can be used as a storage provider for Kubernetes. With StorageOS, capacity from local or attached storage is pooled across the cluster, providing converged infrastructure for cloud-native applications.

Wrap HumanReadablePrinter in tab output unless explicitly asked not to
`kubectl get` was not properly aligning its output due to #40848
Fixes an accidental regression. In general, we should not accept an incoming tabwriter and instead manage at a higher level. Fix the bug and add a comment re: future refactoring.
Get command now uses metadata x-kubernetes-print-columns, if present, in Openapi schema
to format output for a resource. This functionality is guarded by a boolean
flag 'use-openapi-print-columns'.

This commit updates `kubectl describe` to display the new HPA
status conditions. This should make it easier for users to discern
the current state of the HPA.
